Drain hole presence and size are important for water heater drip pans because they allow water to exit efficiently, preventing overflow and floor damage. A properly sized hole (typically 1 inch) ensures compatibility with standard drain fittings and enables continuous drainage during leaks or condensation. Pans like the Wall Mounted Tankless Water Heater Drain Pan feature a 1.32" drain hole, suitable for rapid water removal, while others like the Drain Pan 24" Natural Rubber have a 1" hole. The availability of various drain hole sizes and even custom drilling options, as in the Water Heater Drain Pan 24" Stainless Steel, ensures compatibility with different fittings and plumbing setups.
